First off I do hope you got my sarcasm from the title, Android 4.0 is not really moving up in the world. It has less users than éclair, Android 2.1. Android 4.0 is Google’s latest OS and it is only officially on a few devices, including the Galaxy Nexus, Galaxy S II, Transformer Prime, and more.
Android 4.0 is now running on 2.9% of all Android devices in the world. Now that seems like a small number but last month it was only on 1.6% of devices. Android 4.0 is a step in the right direction for Android and I want to see it on more device as soon as possible. For now though Gingerbread still leads the pack on 63.7% of all devices.
